DOUGH-ROLLING OR DOUGH-SPREADING APPARATUS.

SPECIFICATION forming p'art of Letters Patent NO. 787,273, dated April 11, 1905.

Application fileu September 21,1903. Serial No. 173,965.

To lr'lm/n if 1111/ (OIHI'7ILJ Be it known that l, Josnru Il Burns, a

citizen of the United States of America, residmg at (leveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Dough-Rolling or l)miglefipremling Apparatus; and I hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it per- 1 tains to make and use the same.

This invention relates to improvements in dough-rolling or dough-spreading apparatus more especially designed for rolling or operating upon a chunk or piece of dough and flattening and forming it into an oblongshape and then rolling or operating upon the fiattened and elongated piece ofdtmgh and spreading the latter into an approximately circular shape or layer and overturning the elongated piece of dough between the aforesaid opera- 1 tions.

This invention consists more especially in dough-spreading apparatus comprising a table having a dough-feeding belt or conveyer instrumental in forming the upper side of the said table. means for actuating the said conveyer. another table arranged in suitable proximity to the first-mentioned table and comprising a movable dough-feeding belt or conveyer arranged to receive a piece of dough operated upon and fed by the con veyer of the first-mentioned table, and means whereby a chunk or piece of dough operated upon the lirst-mentioned table is delivered onto the other table and turned over during its delivery to the lastanentioned table.

()ne object of this invention is to perform two operations upon a chunk or piece of dough, and thereby roll or spread the dough into an approximately circular layer and overturn the piece of dough between the two doughrolling or dough-spreading operations.

Another object is to roll clmnks or pieces of dough into the desired form economically and with great facility.

Another object is to first roll a chunk or piece ofdough. and thereby elongate the same, upon an elastic and compressible apron or seat and then actuate the said apron or seat,

and thereby overturn the elongated piece of dough and roll or spread the same into an approximately circular layer.

\Vith these objects in view and to the end of providing a machine or apparatus which is reliable in its operation this invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figurel is a top plan of a machine or apparatus embodying my invention. Figs. and 3 are elevations taken at right angles to each other. Fig. A is a top plan of a portion of the apron-carrying belt or conveyer of the apparatus. Fig. is a section on line :3 5. Fig. a, looking in the direction indicated by the arrow.

Referring to the drawings, A and u designate two dough-rolling tables arranged at right angles to each other, with the table A somewhat higher than the table u. The table A comprises two dough-feeding endless belts or conveyors B and which are actuated simultaneously in the same direction and in unison and form the uppersurface of the said table, with the upper and dough-feeding portions of the said conveyors arranged in the same planehorizontally. 'lhetablecomprisestwo endless belts or conveyers and I, which are l actuated simultaneously in the same direction and in unison and form the upper surface of the said table 1/, with the upper and dough-feeding portions of the said conveyors arranged in the same horizontal plane. The upper and dough-feeding portions of the conveyers and c are arranged at an elevation a suitable distance below the upper and dough-feeding portions of the conveyors B and C. The conveyers B and 6, arranged adjacent to the inner corner formed by and between the tables A and r/, are somewhat shorter .than the conveyers C and c, arranged adjacent the outer corner formed by and between the said tables, as shown very clearly in Fig. 1, to accommodate the feeding of partially-rolled pieces of dough simultaneously by the conveyers B and U to the conveyors and c, respectively. Preferably the conveyor B at the dough-delivering end of the table A somewhat overhangs the conveyer /1 at the dough-receiving end of the table a, and the conveyer O at the dough-delivering end of the table A somewhat overhangs the conveyer c at the doughreceiving end of the table (0. Obviously the conveyers B and O are actuated in the direction required to feed dough rolled thereon, as will hereinafter appear, to the conveyers I) and 0, respectively, and the latter are actuated in the direction required to feed the dough delivered thereto away from the conveyers B and O.

Any approved means for operating the different conveyers may be provided, and each table is provided with suitable means for rolling the pieces of dough fed by the conveyers of the said table.

As shown, the table A comprises two horizontal rolls D and E, which extend transversely of the said table at the upper side and lower side, respectively, of the upper and dough-feeding portions of the conveyers B and O and are arranged at a right angle to the said conveyers. The rolls D and E are arranged in the same plane vertically, and the lower roll E forms a bottom bearing for the upper and dough-feeding portions of the conveyers B and O. The said rolls are supported in any approved manner from the stationary framework F of the table A and are intergeared at one end with each other, as at G, so that the said rolls during their rotation turn in opposite directions, respectively, as required, and one of the gears Gr, employed in establishing operative connection between the rolls D and E, is operatively provided with a sprocket-wheel H, which is arranged in line axially with the respective gear and operatively connected by a chain I with a spocketwheel J, which is operatively mounted on a shaft K, suitably supported from the framework F and arranged parallel with the rolls 1) and E. The longer conveyer O of the table A leads at the dough-delivering end of the said table over a suitably-supported roller L, employed in actuating the said conveyer, and is operatively mounted on or connected with the shaft K, which is operatively provided with a driving-wheel M, to whichpower is applied in any approved manner. The shorter conveyer B of the table A leads at the dough-delivering end of the said table over a suitably-supported roller N, employed in actuating the said conveyer B and operatively provided with a sprocket-wheel O, which is operatively connected by a chain P with a sprocket-wheel Q, operatively mounted, connected with the roller L. Both conveyers B and O of the table A lead at the dough-receiving end of the said table over a guide-roller R, which is supported from the framework F.

The parts are so arranged and timed that chunks or pieces of dough delivered to the conveyers Band (1 in advance of the upper roll D are fed in under the said roll to the conveyers b and 0, respectively, of the table A and rolled, and thereby elongated longitudinally of the conveyers B and C during their passage to the conveyers b and 0.

Each conveyer of the table A is provided at its outer side with aprons S, spaced equidistantly and arranged longitudinally of the said conveyer. Each apron S is attached at its forward end only, preferably by stitching the said apron at the said end, as at T, to and transversely of the respective conveyer, to the said conveyer, so that the said apron is capable of being swung upwardly and in the direction of the table B, as will hereinafter more clearly appear.

The rolls D and E are located, preferably, centrally between the ends of the table A.

A- chunk W of dough to be rolled and spread is placed upon each apron S as the said apron, during the actuation of the conveyer carrying the apron, approaches the roll D. A chunk WV of dough having been placed upon an apron S preparatory to the feeding of the same to and in under the roll D is operated upon during its passage in under the said roll and rolled, and thereby spread longitudinally of the said apron, and consequently longitudinally of the conveyer carrying the said apron. Fig. 1 illustrates the feeding of two chunks of dough to be rolled, one chunk of. dough being rolled, and thereby elongated longitudinally of the table A, and two chunks of dough having been elongated upon the said table and about to be delivered to the conveyers Z) and 0, respectively, of the table a. Of course each apron S, preparatory to the deposit thereon of a chunk of dough, is suitably floured, and the said chunk of dough is floured on top preparatory to its passage under the roll D.

The aprons S of the conveyers of the table A are flexible and yet sufficientl y stifl' to render them capable of swinging upwardly toward and over the table B during the passage of the said aprons around the driving-rollers of the said conveyers. -In dotted lines, Fig. 2, a dough-laden apron is shown swinging from the table A upwardly toward and over the table (6.

Obviously each dough-laden apron of each conveyer of the table A in swinging from over the said conveyer toward and over the respective conveyer of the table a overturns its load-an elongated chunk of doughand deposits the latter onto and transversely of and at a right angle to the said last-mentioned conveyer.

The aprons S of each conveyer of the table A are preferably arranged alternately with the aprons S of the other conveyer of the said table, as shown, so that only one dough-carrying apron of the one or the other of the said conveyers is rolled at one and the same time upon the table A. It is obvious, therefore, that any inequality in the thickness of the chunks of dough delivered to the aprons of the different conveyers of the table Adoes not in- A. llach apron S forms, therefore, an elastic j and compressible seat for a chunk of dough to be operated upon, and although the yielding capability of the seat thus formed is quite desirable l have found that the canvas forms a more suitable surface on which to operate upon the dough than rubber.

To prevent the aprons S of the conveyers B and C of the table A from flapping directly against the conveyers and 1: of the table 1/ during the delivery of the partially-rolled dough from the table A onto the table 11, the stationary framework of the table 11 is pro vided, over each conveyer of the said table 1/ and in suitable proximity to the upper surface of the upper and dough-feeling portion of the said conveyer, with two arms .1, which 3 are arranged transversely of the said conveyer and arranged such a distance apart longitudinally of the eonveyer and in such position relative to the respective apron-carrying eoi'iveyer of the table A that each apron S of the said a iron-carrying conveyer will upon swinging toward and over the table 1/ [lap against the said arms, so that any partiallyrolled dough carried by the said apron will be positively freed from the apron and fall overturned between the said arms onto the respective conveyer of the table 11, and any flour on the said apron will be shaken from the apron and deposited onto and distributed over the overtiu'ned elongated piece of dough. lt will be observed, therefore, that the arrangement of the parts such that a chunk or piece of dough elongated upon the table A is during its delivery from the said table to the [able1/ deposited upon the latter crosswise of the respective dough-feeding conthe actuation of the convcyer carrying the said apron removed from the table 1/ and from over the dough thus delivered onto the said table. and another (hJugh-laden apron approaches the said table. Preferably the arrangement of the parts is such that both conveyers B and U of the table A deliver dough simultaneously to the conveyors and 1;, respectively, of the table 11.

As shown, the table 1/ comprises two horizontal rolls 1/ and 1, which extend transversely of the said table at the upper side and lower side, respectively, of the upper and doughare arranged at a right angle to the said conveyers. The rolls 1/and 1 are arranged in the same plane vertically and preferably about centrally between the ends of the table11 The lower rollc forms a bottom bearing for the upper and dough-feeding portions of the conveyers and 1". The rolls 1/ and 1 are suitably supported from the framework f and are intergearcd with each other, as at 1 so that the said rolls during their rotation turn in opposite directions, respectively, as required. One of the gears, establishing operativeconnection between the rolls (/and 1., is operatively provided with a sprocket-wheel/l, which is arranged in line axially with the respective gear and operatively connected by a chain 1' with a sprocketwheel which is operatively mounted on the shaft supported from the frameworkfand arranged parallel with the rolls 1/and 1 The longer conveyor 0 of the table 11 leads at the dough-receiving end of the said table over a suitablysupported guide roller The shorter conveyer of the table 11 leads at the dough-receiving end of the said table over a suitably-supportedguide-roller. Bothconveyers and c of the table 1/ lead at theopposite end of the said table over a roller r,which is supported from the frameworkf and employed in actuating the said conveyors. The roller r is operatively mounted on or connected with the shaft X, which is operatively provided with a driving-wheel 1/1, to which power is applied in any approved manner. As already indicated, both conveyers B and (l of the table A simultaneously deliver dough to the conveyers and 1', respectively, of the table 1/,- but as the conveyor 1 being adjacent the outer corner formed by and between the tables A and 11 is longer than the conveyor I obviously the simultaneousdelivery of dough from the different conveyors of the table A onto the different conveyers, respectively, of the table 11 will result in the arrangement of the pieces of doughsuccessively delivered to each conveyer of the table 11 alternately with the pieces of dough successively delivered to the other conveyor of the said table 11, so that the upper roll 1/ of the table 11 shall roll only one piece of dough at a time, or, in other words, shall operate alternately upon dough fed by the different conveyors, respectively, of the table l.

By the arrangement of the parts hereinbefore described it will be observed that the partially-r01led and elongated pieces of dough delivered from the different conveyors of the table A to and crosswise of the different conveyors, respectively, of the table 11 are fed to and in under and rolled by the roll 1/ of the last-mentioned table,and thereby spread into an approximately circular layer, as shown.

Fig. l of the drawings illustrates the feeding of a partially-rolled elongated piece of dough to the roll 1/, another elongated piece feeding portions of the conveyers and 1: and l of dough being rolled widthwise by the roll and thereby spread into an approximately circular layer, and two pieces of dough in the form of circular layers ready to be removed from the table a.
